Biocontrol mechanisms by Trichoderma through genomics and proteomics analysis: A review
Soil-borne phytopathogenic fungi pose serious threats to yield of several crops. Biological control is an eco-friendly approach in the effective management of crop diseases. Trichoderma is an important soil-borne fungus, which play an important role in antagonism by secretion of different hydrolytic enzymes. Lentil is an important pulse crop world-wide and its yield is severely affected by wilt...

Halophilic microbes for bio-remediation of salt affected soils
Bacteria inhabiting soil play a role in conservation and restoration biology of higher organisms. The salt affected soils are dominated by many types of halophilic and halotolerant microorganisms, spread over a large number of phylogenetic groups. These microbes have potential for plant growth promotion and release of enzymes under salt stress. Halophiles have thus potential to remediate salt affected soils, enhancing...

Profile of enzymes secreted by Nocardia sp. isolated from sugarcane bagasse leachate and its application in degradative processes of organic matter
Microorganisms are involved in various processes of nutrient cycling, decomposing the organic matter, producing antibiotics, biosurfactants, enzymes for various industrial applications, and may have a direct application in bioremediation strategies. At the beginning of sugarcane crushing season of 2006/2007, samples of leachate of sugarcane bagasse (which was accumulated since the 2005/2006 season) were collected in a...

Effects of climate change on plant associated microbial communities and enzyme activities
Environmental alterations leads to fluctuations in the soil microbial population and soil enzyme activities, as different weather parameters affect microbial biota and their activities in rhizospheric soil of crop. An agroclimatic study was carried out to study the effect of environmental alterations on soil microbial population and enzyme activities in rhizospheric soil of rice and wheat crop. Rice and wheat crop were...

Bot canker pathogens could complicate the management of Phytophthora black pod of cocoa
Black pod is a major hindrance to cocoa production in Nigeria. It is caused by three different Phytophthora species with Phytophthora megakarya as the most important species in Nigeria and West African sub-region. Phytophthora spp. may enhance infections by opportunistic pathogens such as members of the Botryosphaeriacea that cause branch and trunk cankers in many woody plants across the world. Botryosphaeriacea has not...

The specific nutrient synergy and their effect on the reduction of pathogens resistance to antibiotics
The high level of pathogens resistance is becoming a huge problem in the health care system. The difficulty to treat recurrent infections also contributes to the spread of resistant microorganisms in the environment. The antibacterial therapy is very often not effective and costly. On the other hand, there is a growing interest in using natural plant components as effective antibacterial agents and valuable complement...

Standardization of inoculation technique of sugarcane smut (Ustilago scitaminea) for evaluation of resistance
Different inoculation techniques viz. inoculation of sets by dipping in spore suspension, bud inoculation with hypodermic syringe, bud wrapping by cotton swab dipped in smut suspension and inoculation of underground bud at the time of tillering (end May) were tested to screen against sugarcane smut in the field as well as in the laboratory conditions. In the field, out of the tested inoculation techniques, the maximum...

Epidemiology of bovine tuberculosis in Butajira, Southern Ethiopia: A cross-sectional abattoir-based study
A cross-sectional study was conducted at Butajira Municipality abattoir from December, 2009 to April 2010 to investigate the epidemiology of bovine tuberculosis (bTB) in Butajira, Southern Ethiopia. Postmortem examination, mycobacterial culturing and multiplex genus typing techniques were used. An overall prevalence of 9% (40/446) of the animals examined harbor gross tuberculous lesions up on detailed post-mortem...

Demographic and microbiological profile of cystic fibrosis in Durban, South Africa
Cystic fibrosis (CF) necessitates long-term treatment with multiple antibiotics creating selection pres-sure for the development of antibiotic resistance in infecting and/or colonizing organisms, impacting on disease management, morbidity and mortality. Sputum samples were obtained from patients attending the only two CF clinics in Durban over a year. The patient demographics and clinical data were recorded. Bacterial...

Isolation and characterization of bacterial symbiont Photorhabdus luminescens SL0708 (Enterobacteriales: Enterobacteriaceae)
Photorhabdus spp. bacteria are associated with infective juveniles of entomopathogenic nematodes of the Heterorhabditidae family. After entering the host, these bacteria cause septicemia and kill the insect within 48-72 h. The objectives of this study were to isolate and identify the symbiont bacteria of the Heterorhabditis sp. SL0708 entomopathogenic nematode, isolated in Valle del Cauca, Colombia. To this end, we...
